| titleOfInvention | Preparation method of piperazine structure-containing DOPO derivative modified flame-retardant epoxy resin |
| abstract | The invention discloses a preparation method of a piperazine-structure-containing DOPO derivative modified flame-retardant epoxy resin. The preparation method comprises the steps of stirring and mixing the epoxy resin and the DOPO derivative containing the piperazine structure uniformly, then adding the curing agent, continuously stirring and mixing to obtain a uniform solution, finally pouring the mixed uniform solution into a preheated mold for curing, naturally cooling to room temperature after curing, and demolding to obtain the corresponding modified flame-retardant epoxy resin. The structure of the DOPO derivative containing the piperazine structure contains secondary amine and tertiary amine, aromatic ring, P, N and other flame-retardant elements, can participate in the curing reaction of the epoxy resin, improves the compatibility, endows the modified epoxy resin with excellent transparency, flame retardance, mechanical and thermal stability, and has wide application prospect. |
